Abstract

A method of fingerprint recognition for a fingerprint sensing circuit includes steps of: performing a first fingerprint sensing process including a first exposure operation and a first readout operation under a first light spot setting; and performing a second fingerprint sensing process including a second exposure operation and a second readout operation under a second light spot setting. Wherein, a host performs a first fingerprint recognition in response to the first fingerprint sensing process; and wherein, the second light spot setting and the first fingerprint recognition are performed simultaneously.
